This report presents a diode-pumped solid state (DPSS) high peak power laser with output energy of 300 mJ, operating frequency of 300 Hz, and pulse width of less than one nanosecond (FWHM) which corresponds to peak power of 300 MW at one micrometer emission wavelength. The laser system consists of a master oscillator power amplifier (MOPA) configuration with the output energy of one millijoule from the oscillator, the output energy of up to 15 millijoules from the pre-amplifier and the output energy of 300 mJ from the power amplifier. The transversal mode is close to the single mode with M2 less than 1.5 and the lasing wavelength is 1064 nm. The MOPA system is well packaged in a compact footprint of 2×3 square feet.
